ISIS executes 19 girls for refusing to have sex

ISIS fanatics have executed 19 women for refusing to have sex with its fighters, a Kurdish official has said.

He claimed the women were being held hostage in Islamic State's stronghold of Mosul, Iraq, which the terror group seized in June last year.

Meanwhile a UN envoy investigating Islamic State's vile sex trade has said 'girls get peddled like barrels of petrol' and one can be bought by six different men.

She also verified a disturbing ISIS document which suggested the extremists sell the Yazidi and Christian women and children they have abducted, with girls aged just one to nine-years-old fetching the most money.

ISIS stormed the Sinjar district in northern Iraq last year and captured hundreds of women belonging to the Yazidi community, who the Islamists view as heretics.
